    <ns1:language>en</ns1:language>
    <ns1:description language="en">Abstract: An efficient method has been proposed to recovering substantial amounts of copper from re-flotation tailings and reducing the environmental impact of flotation tailings by a combined hydrometallurgical process which includes High Pressure Leaching (HPL)-Solvent extraction (SX)-Electrowinning (EW) processes. As a result of HPL using water or sulfuric acid as leaching solution, high copper leaching rate (&gt;95%) was obtained even with water. Then, the copper concentration in the stripped solution reached 44.8 g/L and the iron concentration was 1.4 g/L by the SX tests using LIX-84I as extractant. Moreover, it was confirmed that as lower iron concentration in the electrolyte for the copper electrowinning process, the better the current efficiency of copper electrodeposition.</ns1:description>
